To all whom mag concern.-

Be it known that I, ALoNzo C. MORSE, a at Shelby, in the county'of Richland and tate of- Oh1o, have mvented'certain new and useful Improvements in Orutches, of which the I followin is as ecific'ation, that will enable [and the side members 'those s I and 1t consists of certain features.

led int c art to' which my Invention ertains to make and use the same, reference ein had to the accompanying drawings,

whic form a part thereof.

My invention relates to crutches. Its object' 1s to make them of light metallic of constructlon, as will hereinafter be specifically described and claimed.

show my invention in general form and details of construction now deemed most desirable by me, Figure 1-is aside elevation of a steel tubular crutch embodying thefeatures 'of my invention 2 is a viewof the upper end of the crutch, showing thearm-piece in section on the line 2 2 of Fig. 4. Fig. 3is a sectional view of the same on the line 3 3 of Fig. 2. Fig. 4 is a iso l is a transverse plan view of the top of the arm-piece. Fig. 5 section through the cross or hand bar and the side members on the line 5 5 of Fig. 1.

the lower end of Verse section of the same on the line 7 7 of three times the scale of Fig. 1.

v In my crutch the two side members A A' Fig. 6; Figs. 2m 7, inclusive, are drawn on are, composed, preferably, of half-round or D- shaped steel tubing arranged with their fiat faces a a facing inwardly. The'arm-piece B is also composed of a piece of half-round steel I which pass through apertures in the'flat faces correspond with the sections of the side members A A, which pass through these apertures and abut against the inner surface of the rounded top and are brazed in place.

At a suitable distance below the to piece the space between the side mem ers is spanned by the cross-bar or hand iece C, composed of round, steel tubing an preferably made' on diminishing taper from the center toward its ends. against the flat inner faces bers and of the side memare provided with metallic plugs c,

tubing Fig. 6 is a vertical section of the crutch. Fig. 7 is a trans-- a curved arm-piece o side members which These ends abut of the side members andare brazed to these members and to the cross-bar.

Toward the lower end of the crutch the side members are brought together with their flat faces in contact and are embraced by the,

end of a round tube D, the upper end of the ends of the members are secured therein by brazing or a rubber tip or cushion F. In the accompanying drawings, which The shank e is internall as shown, and the cushion as a neck or stem f, which is screwed into the socket'to hold the cushion in lace.

A crutc screw-threaded,

constructed as described and anded to form a socketd a shank e,'which extends up shown is handsome, li ht and strong, and remarkably-durable and eing without bolted or screwed joints to become loosened by strains and wear will in ordinary service last a lifetiine. By actual test one of these crutches weighin abundantly strong for a man weighing over two hundred pounds.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

1. In a crutch composed entirely of metal-- lic tubing, a curved arm-piece of D-shaped tubing with its flat side down, side members composed of D-shaped tubing with their flat sides in, suitably joined to the arm-piece and brought together at theirlower ends, a tubular cross-bar united at its ends to the side members and a tubular lower end piece having a socket at its u per end to receive the contacting lower en s of the side members, all the parts being suitably joined by brazing or otherwise, substantiallyas set forth.

2; In a crutch com osed of metallic tubing D-shaped tubing with its fiat side down, side members com osed of D-shaped tubing and'arranged with t eir flat sides in, apertures in the lower fiat side of the arm-piececorresponding to the shape of the pass through said apertures and abut against inner surface ofthe top of the arm piece, substantially as set forth; 7 a .3.[In a crutch a tubular metallic armpiece,- side members composed of .D-shap'ed g one pound and seven ounces is" side members being brought together with their fiat sides in contact and a tubular end piece socketing the contacting lower ends of 15 the side bars and forming the lower end of the crutch, substantially as set forth.

In testimony whereof I have signed my name to.this specification in the presence of two subscribing Witnesses.
